概括
动物行为中的积极对比,即对不变的时间表组成部分的响应增加,可能并非源于主观价值的增加. 子更喜欢非灭绝组件,这表明了最大限度地利用强化剂的策略.
科学领域:
- 动物行为 动物行为
- 行为心理学 行为心理学
- 操作者调节的条件.
背景情况:
- 积极的对比通常由一个不变的时间表组件的主观价值的增加来解释.
- 当多个时间表中的一个组件经历强化率下降时,就会观察到这种现象.
研究的目的:
- 调查子中正对比的潜在机制.
- 挑战传统的假设,即积极的对比结果从主观价值的增加.
主要方法:
- 子被暴露在多个时间表中,其中一个刺激 (A) 随后是灭绝,另一个刺激 (B) 则是可变的间隔时间表.
- 测量了行为对比 ( rate) 和刺激偏好 (A和B之间的选择).
主要成果:
- 子在刺激A的存在下表现出更高的率 (行为对比).
- 然而,子始终更喜欢刺激B,没有灭绝的刺激.
- 这种偏好与主观价值假设相矛盾.
结论:
- 在这种情况下,积极的对比可能不仅仅是由于不变组件的主观价值的增加.
- 这些发现表明,正对比可能部分是由生物体在灭绝期开始之前获得所有可能的增强剂的策略驱动的.

Mate Choice
Mate choice—the decision about whom to mate with—is a type of natural selection, since animals must reproduce to pass down their genes. Mate choice is also called intersexual selection because the behavior occurs between the sexes.
Testing a Claim about Population Proportion
A complete procedure for testing a claim about a population proportion is provided here.
There are two methods of testing a claim about a population proportion: (1) Using the sample proportion from the data where a binomial distribution is approximated to the normal distribution and (2) Using the binomial probabilities calculated from the data.
The first method uses normal distribution as an approximation to the binomial distribution. The requirements are as follows: sample size is large...

Dose-Response Relationship: Overview
Agonists can bind with and activate receptors, resulting in the formation of drug-receptor complexes. Once formed, these complexes catalyze many biochemical processes at the cellular level and subsequently induce a pharmacologic response. The degree of response is directly proportional to the fraction of activated receptors, which in turn, depends on the concentration of the drug at the receptor site as well as the sensitivity of the receptor. An increase in the administered dose contributes to...
Dose-Response Relationship: Selectivity and Specificity
Drugs exert their therapeutic effects by interacting with receptors, enzymes, or ion channels that are present throughout the human body. The strength and duration of the interaction between a drug and its target receptor are characterized by the selectivity and specificity of the drug. Selectivity refers to a drug's strong preference for its intended target over other targets. For instance, isoprenaline, a non-selective β-adrenergic agonist, interacts with both β1- and β2-adrenergic receptors...
Factors Influencing Attraction IV: Reciprocity
Reciprocity in attraction is fundamental to social and romantic relationships, shaping how individuals form and maintain connections. The psychological principle underlying this phenomenon is that people tend to like those who express liking toward them. Balance theory supports this tendency, suggesting that mutual attraction fosters psychological harmony, whereas one-sided affection leads to discomfort and cognitive dissonance.The Psychological Mechanisms Behind ReciprocityWhen individuals...
